Abstract

A wearable device is disclosed. The wearable device may include a display, a lens, an illuminator, an image sensor, and at least one processor. The display may be configured to present images. The lens may be configured to provide a view of the display to an eye of a user. The illuminator may be configured to illuminate the eye. The image sensor may be configured to detect illumination reflected by the eye. The at least one processor may be configured to cause the display to present an image, receive data from the image sensor, determine a gaze direction of the eye based at least in part on the data from the image sensor, and cause at least one of the display or the lens to be moved until the gaze direction is directed toward the image.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A wearable device, wherein the wearable device comprises:
 a display configured to present images; 
 a lens configured to provide a view of the display to an eye of a user; 
 an illuminator configured to illuminate the eye; 
 an image sensor configured to detect illumination reflected by the eye; and 
 at least one processor configured to:
 cause the display to present an image; 
 receive data from the image sensor; 
 determine a gaze direction of the eye based at least in part on the data from the image sensor, the gaze direction indicative of the eye not focused on the image; and 
 cause at least one of the display or the lens to be moved until the gaze direction indicates the eye is focused on the image. 
 
 
     
     
       2. The wearable device of  claim 1 , wherein:
 causing at least one of the display or the lens to be moved comprises moving at least one of the display or the lens toward or away from the eye. 
 
     
     
       3. The wearable device of  claim 1 , wherein:
 causing at least one of the display or the lens to be moved comprises causing the display to be moved. 
 
     
     
       4. The wearable device of  claim 1 , wherein:
 causing at least one of the display or the lens to be moved comprises causing the lens to be moved. 
 
     
     
       5. The wearable device of  claim 1 , wherein:
 causing the display to present an image comprises causing the display to present a grated image. 
 
     
     
       6. The wearable device of  claim 1 , wherein:
 the processor is further configured to cause at least one of the illuminator or the image sensor to be moved. 
 
     
     
       7. The wearable device of  claim 6 , wherein:
 causing at least one of the illuminator or the image sensor to be moved comprises causing the illuminator to be moved. 
 
     
     
       8. The wearable device of  claim 6 , wherein:
 causing at least one of the illuminator or the image sensor to be moved comprises causing the image sensor to be moved. 
 
     
     
       9. The wearable device of  claim 6 , wherein:
 the processor causes at least one of the illuminator or the image sensor to be moved based at least in part on the data received from the image sensor. 
 
     
     
       10. The wearable device of  claim 9 , wherein:
 the processor is further configured to determine an inter-pupillary distance based at least in part on the data received from the image sensor; and 
 causing at least one of the illuminator or the image sensor to be moved based at least in part on data received from the image sensor comprises causing at least one of the illuminator or the image sensor to be moved based at least in part on the inter-pupillary distance. 
 
     
     
       11. A method for displaying images to a user, wherein the method comprises:
 causing a display to present an image through a lens to an eye of a user; 
 causing an illuminator to illuminate the eye of the user; 
 receiving data from an image sensor detecting illumination reflected by the eye; 
 determining a gaze direction of the eye based at least in part on the data from the image sensor, the gaze direction indicative of the eye not focused on the image; and 
 causing at least one of the display or the lens to be moved until the gaze direction indicates the eye is focused on the image. 
 
     
     
       12. The method for displaying images to a user of  claim 11 , wherein:
 causing at least one of the display or the lens to be moved comprises moving at least one of the display or the lens toward or away from the eye. 
 
     
     
       13. The method for displaying images to a user of  claim 11 , wherein:
 causing the display to present an image comprises causing the display to present a grated image. 
 
     
     
       14. The method for displaying images to a user of  claim 11 , wherein the method further comprises:
 causing at least one of the illuminator or the image sensor to be moved. 
 
     
     
       15. The method for displaying images to a user of  claim 14 , wherein:
 causing at least one of the illuminator or the image sensor to be moved based is based at least in part on the data received from the image sensor. 
 
     
     
       16. A non-transitory machine readable medium having instructions stored thereon for displaying images to a user, wherein the instructions are executable by one or more processors to cause the one or more processors to at least:
 cause a display in a wearable device to present an image through a lens to an eye of a user; 
 cause an illuminator to illuminate the eye of the user; 
 receive data from an image sensor detecting illumination reflected by the eye; 
 determine a gaze direction of the eye based at least in part on the data from the image sensor, the gaze direction indicative of the eye not focused on the image; and 
 cause at least one of the display or the lens to be moved until the gaze direction indicates the eye is focused on the image. 
 
     
     
       17. The non-transitory machine readable medium of  claim 16 , wherein:
 causing at least one of the display or the lens to be moved comprises moving at least one of the display or the lens toward or away from the eye. 
 
     
     
       18. The non-transitory machine readable medium of  claim 16 , wherein:
 causing the display to present an image comprises causing the display to present a grated image. 
 
     
     
       19. The non-transitory machine readable medium of  claim 16 , wherein the instructions are further executable to at least:
 cause at least one of the illuminator or the image sensor to be moved. 
 
     
     
       20. The non-transitory machine readable medium of  claim 19 , wherein:
 causing at least one of the illuminator or the image sensor to be moved based is based at least in part on the data received from the image sensor.
